UPnP troubleshooting steps

UPnP is short for Universal Plug and Play - it is a feature that works with some compatible routers to open the required ports automatically. If Vuze is crashing often, you should try to disable UPnP in the options!

Go to the Advanced options: Menu (View > Advanced)

On Windows:
Menu [Tools > Options > Plugins > UPnP (sub-menu)]

On Mac:
Azureus > Preferences > Plugins > UPnP (sub-menu)]

Vuze needs to open a connection for the outside world, through a port in your router. Typically and by default (though not recommended anymore) port 6881. Let us use port 55321.

We need to tell your router that all that arrives on port 55321 has to be directed to your machine. UPnP in Vuze can do that for you, unless:

• your router doesn't support UPnP. Some routers, even if they are compatible with UPnP, have problems with this. In that case you need to dive into your router's manual and look up port forwarding.

1.WRT54G v4(/5?) - doesn't do UDP/TCP on same port properly - use different ports for the 'Incoming TCP Listen Port' and DDB. Also disable the UDP tracker protocol if needed.

User has reported that with v5 a hard-reset of the router was needed to get things working.
2.WAG354G - very slow at releasing port mappings on exit. This causes Vuze to appear to hang when quit for several minutes. Avoid this by configuring Vuze not to release on exit.

Reporting UPnP problems:

If you experience UPnP problems, then you should have a look at the log view for the UPnP plugin (Plugins > Log Views > UPnP). The information there will describe how Vuze has tried to set up the appropriate connections using UPnP. If you need some help understanding what the messages mean (when things aren't working), copy the text and post it to the Vuze forums.

If you are asked to get the full UPnP log, you can do this by going to the UPnP options, and enable the "Output full debug information to log" setting. Then restart Vuze - the full UPnP debug information will be printed in the UPnP log view. This setting is only available in v3.0.0.9 and later.

If you have an earlier version of Vuze which does not have this setting, then follow these steps:
